The state weather bureau on Saturday said it is monitoring two low-pressure areas or LPAs inside the Philippine Area of Responsibility.

In its latest weather bulletin, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration, said the first LPA was last tracked over 530 kilometers east of Catarman, Northern Samar.

The second LPA was spotted 235 kilometers west of Dagupan City, Pangasinan.

PAGASA hoisted rainfall advisory as southwest monsoon or 'habagat' affects Southern Luzon, Visayas, and Mindanao.

The weather system will particularly bring light to moderate with at times heavy rains in Antique, Iloilo, and Negros Occidental.

The Yellow warning level was earlier raised over the Guimaras (Sibunag, San Lorenzo, Nueva Valencia, Jordan, Buenavista); Antique (Anini-Y, Hamtic, Tobias Fornier, San Jose, Sibalom); Iloilo (San Joaquin, Miagao, Igbaras, Guimbal, Oton, Tigbauan, Pavia, Iloilo City, Leganes, Zarraga, Dumangas); Negros Occidental (Silay City, Talisay City, Bacolod City, Pulupandan, Bago City, Valladolid, San Enrique, Pontevedra, Hinigaran, Himamaylan City, Binalbagan, Kabankalan City, Ilog, Cauayan, Sipalay City, Candoni, Hinoba-An).

With this weather condition, PAGASA warned flooding is possible in low-lying areas and rain-induced landslides must be expected in mountainous areas.

PAGASA said Metro Manila, the rest of Luzon, and Visayas will experience cloudy skies with scattered rain showers and thunderstorms.

While Mindanao will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms.

PAGASA said light to moderate winds and slight to moderate coastal waters are forecast for the whole country.
